[gdal-dev] Having overview URL inside VRT

[Denis Rykov]

Hi all,

I know that it possible using GDAL VRT describe overviews with <Overview>
tag.
But it is not very convenient way in many cases. I'm wondering whether it
is possible to put a link to overview *.ovr file inside a VRT?
In some scenarios we cannot use a relative path and assumption that *.ovr
should be located in the same place alongside the original raster doesn't
work.
Does it make sense to have such feature for VRT?

Thanks.
